Say hello to your new power couple.

After Ariana Grande teamed up with boy bander Nathan Sykes of The Wanted on "Almost Is Never Enough," a sweet love song for the Mortal Instruments: City of Bones soundtrack, rumors started flying that the stars were dating. But with lyrics like, "If I would have known that you wanted me / The way I wanted you / Then maybe we wouldn't be two worlds apart / But right here in each others arms," that was inevitable.

Turns out, they totally meant what they were singing. After the duo was snapped by the paparazzi (and were, in fact, in each others arms) at Disneyland this weekend, they took to Twitter to 'fess up. Nathan said, "So, I guess it's obvious now...thanks to everyone who is being so lovely. I'm so happy," and Ariana retweeted him. (Related: Is Twitter official is the new Facebook official?)

We interviewed Ariana a few weeks ago, and she went on and on about Nathan, even calling him "amazing." Technically, she was talking about his voice in the song, but still. "I recorded 'Almost Is Never Enough' as a solo ballad for my album," she told us. "Then a few days later, I got an email from my manager, Scooter Braun, that said: 'Check this out.' It was 'Almost Is Never Enough' with Nathan on it. I was dying, it was perfect, and he's amazing." Here's to many more perfect collaborations—of all kinds—in the future.
